B01, SBN 2000: Improved EPA/MACT Reporting of Emissions from Drying Operations Under Vacuum (Improvement)
When executing a drying operation that is under vacuum, there are two sources (and two calculation methods recommended by the EPA regulations) for how to calculate and report emissions:
a) Related to the drying step itself
b) Related to pulling vacuum
In previous releases of SuperPro Designer, the simulation engine will add up the two emission results and report them together in association to this operation. Starting with this release, we will be reporting the contributions from each calculation separately.
B01, SBN 2000: Warning is Displayed if Condenser Temperature Setting Higher than Vessel Content's Temperature (Improvement)
When requesting the controlled emissions from a procedure, the user is required to provide an operating temperature for the associated condenser (part of the EPA-MACT Options). If the temperature setting of the condenser is found to be HIGHER than any of the operations in the procedure, a warning will be issued (see below) and the Efficiency reported will be 0% (instead of a negative value).
B01, SBN 2000: Printing of Amounts in the EPA/MACT Report that Are Below the Precision Setting Will Now (Optionally) Show the Value in Exponential Format (instead of 0.00) (Improvement)
It is not uncommon that values of emissions are quite small and often below the precision specified for the report and that quantity (e.g. "amount per batch", see below).
If that is the case, previous releases will show a "0.00" value and therefore it would not be obvious if the amount is barely under the precision level (e.g. 1.0E-3) or quite low (e.g. 1.0E-6). Starting with this release, if the number is below the specified precision, the number will be included in exponential form (see below)
... if the related option is activated on the report options tab:
This features is currently only available in the Emissions and EPA-MACT report.
B01, SBN 2000: Global Warming Potential Analysis now Included in the Lactoferin Example (Improvement)
The example has been expanded in its scope to now include a Global Warming Potential evaluation. The values for single carbon dioxide–equivalent (CO₂eq) values for raw materials, power sources and energy sources have been included. The CO₂eq value represents the aggregate climate impact of all relevant emissions. GWP is a key element of Life Cycle Assessment (LCA), a standardized, quantitative methodology used to evaluate the environmental impacts of a product, process, or service across its entire life cycle. Users are urged to follow the analysis in this example to learn how to apply similar analysis to their models.
The example can be found in the Neutraceuticals collection of sample models included with SuperPro Designer (all under the EXAMPLES folder).
B01, SBN 2000: Cloth Filtration Operations: Table Columns Have Been Widened (Improvement)
The cloth filtration operations have wider table columns in order to show the reported % Removed better (see below):
B01, SBN 2000: Neutralization Operation: Error in Energy Balance Calculations (Bug Fix)
Due to a glitch in the code, the enthalpy balance around neutralization operations was not carried out properly (in some cases) and therefore an incorrect amount of heating/cooling was reported. This issue has been fixed.
B01, SBN 2000: Neutralization Operation: Didn't Recognize the Presence of Neutralization Agent (Bug Fix)
Due to a glitch in the code, the operation in some cases did not recognize the presence of the designated neutralization agent in the feed. This issue has been fixed.
B01, SBN 2000: Gasification Operation: Heat Duty Calculation Could be Incorrect (Bug Fix)
Due to a glitch in the code, when the final temperature is set, the calculated heat duty is lower by a factor of 1,000 due to a conversion issue from kJ/kg of fuel to kW. Similarly, when the user sets the heat duty, the value is incorrectly converted from kW to kJ/kg, causing the final temperature calculation to fail or be incorrect in some cases did not recognize the presence of the designated neutralization agent in the feed. This issue has been fixed.
B01, SBN 2000: Copy-and-Paste of Transportation Unit Procedures May Lead to a Crash (Bug Fix)
Unit procedures that represent long distance transport (e.g. by plane, train or truck) do not have an equipment resource behind them. This used to cause an issue when copying-and-pasting them in the same or different flowsheet. This issue has been fixed.
B01, SBN 2000: Transforming a Discrete Intermediate Stream to an Input Stream Would also Incorrectly Convert the Stream to Bulk (Bug Fix)
When you remove (by clicking-and-dragging) a procedure input stream from its source, the program automatically transforms it to a process input stream. When this task was carried on a discrete stream, the stream was inadvertently transformed to a bulk input instead of a discrete input stream. This issue has been fixed.
B01, SBN 2000: Issues Related to the Page Displaying Properties of an Electrode (Bug Fix)
When visiting the definition of an electrode consumable, the page displaying its properties had the following glitch: if you select the electrode pair option and then select one of the other options (cathode or anode) the 'Calculated' options for the purchase and disposable consts were disabled by mistake. This is now fixed.
B01, SBN 2000: Electrowinning Consumables Page Glitch (Bug Fix)
The page that displayed the properties of an Electrowinning consumable demonstrated the following odd behavior: the thickness and density of an electrode-type consumable were only displayed when the electrode's purchase cost per unit or its disposable cost per unit was not set by user. This has now been fixed.
B01, SBN 2000: The M2E Factor Has Been Removed from the Continuous Evaporation i/o Interface (Bug Fix)
This factor is no longer used by the model but was still inadverntly displayed on the i/o dialog of the continous evaporation operation. This has now been fixed and the factor is no longer there.
B01, SBN 2000: Pneumatic Conveyor Sizing Units Fixed (Bug Fix)
The sizing units for the throughput in a pneumatic conveyor should be in mass throughput not volume. This caused an incorrect cost reported for the purchase cost of the unit. This has now been fixed.
B01, SBN 2000: Gas Expansion Operation Incorrectly Reported a HX Agent as Being Used (Bug Fix)
A gas expansion operation would report a heat transfer agent as being used even though the condenser was not checked to be engaged. This has now been fixed.
B01, SBN 2000: Input Data Report (IDR): Occasional Crash While Generating the IDR Report (Bug Fix)
When the IDR report included descriptions of operations that operate in adiabatic mode, there is no associated heat transfer agent. In such cases, the report would inadvertently try to include the agent's name and it would generate a crash. This has now been fixed.
B01, SBN 2000: Tray Drying Operation Produced Incorrect Output when the Temperature of the Final Solids Was Higher than One of the Volatile Components (Bug Fix)
This has now been fixed.
B01, SBN 2000: Bulk-to-Discrete Operation: Now It Accounts for Heat Dissipation (Improvement)
This was inadvertently missed before but it is now included in the heat balance calculations.
B01, SBN 2000: Filling and Labeling Operations Produce a Warning when the Adjustable Stream does not Have Any Flow (and it is not a process input) (Improvement)
If that situation occurs, then the simulation engine cannot back-propagate the required (adjusted) flow and therefore a warning should be produced. This was missed before.
B01, SBN 2000: Emission Calculations Will NOT Produce an Error/Warning if Nothing Has Been Checked as Emitted (Improvement)
Previously, when the emission calculations produced no emissions, a warning/error was generated and reported on the Warnings/Errors tab since it was assumed that something went wrong with the VLE calculations. However, there is a trivial case were nothing is calculated as emitted: when the user has not elected anything to be emitted or those checked as emitted are not present in the vessel. If that is the case, now, the error/warning is suppressed to avoid confusing the user.
B01, SBN 2000: Exporing Information to SchedulePro's Database Has Been Improved (Improvement)
Several new features that were added to SuperPro were not exported in the SchedulePro database. Starting with this release all such information is exported.
B01, SBN 2000: Properties of the Key Consumable Are Now Displayed on the Equipment tab (first tab) of Filters, Chromatography Columns (Improvement)
Some of the key characteristics of the required consumable in equipment that need such a consumable (e.g. membrane filters, chromatography columns) are now displayed on first tab of the Equipment dialog.
B01, SBN 2000: Several New Properties of Operations and/or Equipment Are Now Accessible by the COM Engine (Improvement)
After users' requests, several new properties of operations and/or equipment are now available to be fetched and set by the COM engine interface of SuperPro Designer.
